FlyingAg / Hein Ranch Co.

Verifying FlyingAg / Hein Ranch Co. runs through three independent checks: Part 107 via the FAA Airmen Inquiry, Part 137 via the issuing FAA Flight Standards office, and the state aerial-category pesticide applicator license via the receiving state's department of agriculture. In California the state credential is issued by CDPR (CalEPA); you can ask the operator for the applicator license number and verify it with the agency directly. Pair that with a current chemical-drift COI and the Section 44807 exemption number for due diligence.

Typical drone spraying rates of $18 to $35 per acre in the region typically covers the application itself: drone calibration, GPS-guided mission planning, mixing and loading product into the tank, the labor and machine time to fly the field, and a written FIFRA Part 170 application record (date, time, product, EPA reg number, rate, weather, field ID). Pesticide product, surfactants and adjuvants are usually supplied by the farmer and excluded from the per-acre rate. Common surcharges include long travel past the operator's standard radius, after-hours or emergency turnaround, fields with steep terrain or significant obstructions, and minimum-acreage charges below a stated field size.
